Applicat ion-filed March 22, 1921. Serial in. 454,555.

To alZ whom it md i Be'it known that EUGENE Tonnnr, a citizen of the United States, and a resident of Holmes, Dutchess'CouQnty, and Stateof New York, have inventedvcertainjnew and useful Improvements in Coil Wind1ng Ma chines. of which the following is a specification.

This invention" relates to the construct on of fiat spiral inductancecolls like those, co,v-

ered in my Patent No. 1.372.850, of March These coils each consist of a wire which is wound spirally and interlaced to opposite sides of the radiating arms of a suppo'rtlng disc of fiat insulatingmaterial, and the eneral objects of the invention are to prov ea simple and'practical machine for automaticallyv winding the wire on these cores.

Other special objects are'to provide amachine which will operate rapidlyand auto matically and which will lay, the wire evenly and firmly in the slots of the core.

In the accompanymgdraw ngs I have illustrated practical commercial embodiments of the invention, but wish it'i'mde'rstood that the physical structure may be modified in various ways without departing from' the true spirit and scope of'the invention.

Figure 1 is a side view oft'he machine.

Figure 2 is a top plan view of the same.

Figure 3 is an enlarged cross sectional view as taken on substantially the plane of the line 33 of Figure 2.

Figures 4 and 5 are broken part sectional detail views illustrating thawinding of the wire to'opposite' sides of the radiating arms of tilieore Figures (5 and Tare broken side and plan views respectively of a modified form of drive.

In the machine illustrated, the flat core disc 10 is temporarily sup orted, during the winding operation, on a sf aft 11, being detachably secured thereon between relatively fixed and movable clampingdiscs 12 and 13, the latter having a screw-threaded connection at 14 with the end of the supporting shaft, and being provided with a wing nut or other hand-hold 15 by which it can be read ily turned to secure the core in position.

The wire, which is designated 16, is wound in the slots 17 provided between the radiattion.

ing arms'of the core and to insure a definite position of the core on the supporting shaft, I have shown the fixed clamping flange 12 as provided with an outstanding finger 18 havin an angularly turned end as shown at 19 in figure 3 to enter in the foot of one of theseslot'skwl en the core is slipped over the endof the shaft;

To weave the Wire back and forth to op-' posite'. sides of the radiating arms, as the core is rotated, I provide a tubular wire guide 2(lthroughwhich the wire passes and which in the machine shown, is reciprocated to opposite sides ofthe central plane of the core disc b ineans of an oscillating arm 21 XVhlQlLlSPIVOt Qd at 22 on the base of the machine and'is swun backandrforth bya link connection22' pivoted to the swinging arm -at;23 (Figure 3)wa nd connected with a strapfit'encirclingthe eccentric 250n the driveshaft 26, which in this particular machine, stands at. 'a right angle to the core shaft 11.-

I: y i

As the winding builds up in the slots, it becomes necessary to relatively lower the point at which the-wire is guided so as to lay the wire firmly in the slots on top of the preceding com'olutionsand so as to avoid the corners of the radiating aims. This will be understood particularly from Figures 1 and 4.

To thus keep the lay of the wire at the proper level or angle, I provide. in the present machine, means for automatically lowering the wire guide as the winding progresses, said means GOIIlPI'lSiIIg a snail cam 27 engaged by an arm 28 on the rock shaft 29 which carries an outstanding how or yoke 30 having a straight guide or track 31 at the free end thereof on which the wire guide 20 rests, said wire guide being vertically 'slidahle in a slot 32 in the upper end of the swinging arm so that'it may follow the lowering movement of the supporting yoke.

The main drive shaft is operated in the present disclosure by a belt engaged over a pulley 33 fixed on said shaft and this pulley is also shown provided with a handle 34 by which the shaft may be turned, if desired, when setting up the parts ready for opera- This also enables the machine being operated by hand in case no power is available.

said cam shaft.

'This particular s hv bevel gearing In the first form of the invention shown, the core supporting shaft 11 is operated intermittently by the engagement of the ends of a transverse pin on said shaft with successive openings 36 provided therefor in a. drive disc 37 fast on theshaft 11. To hold the shaft 11 each time it is' advanced, this disc is shown as provided with ratchet shout ders 38 engaged by a holding pawl 39.

The snail cam is shown as carried by a shaft 40 and as intermittently driven by the engagement of an outstanding tooth 41 on shaft 11 with the teeth of a gear 42 fast on This cam shaft lilrewise is shown as held'against retrograde movement by a holding pawl 43 engaging with the teeth of this gear.

To steady the radial arms of the core while the wire is being wound thereon, I have shown an overstanding guide 44 carried by a rock shaft 45 and provided with a slot 46 receiving the outer ends of the arms.

method out of the way when the core is being positioned on its supporting'shaft, said' arm being held in its" downward position by a weight 46' adjustably secured by a screw 47, the downward motionof theiguide being limited by an arm 48 contacting with a suit able stop shoulder 49 (Figure 1.);

The operator is autometicallynotified in the present disclosure whenthe coil is fully wound, by a signal consisting of the bell orgong 50 arranged to be struck by the hammer 51 carried by a lever 52 pivoted on the base at 53 and heldvby' thespring 54 engagement with acamcIement SS on shaft 40.

At the coil starting position, the snail cam may be provided with a notchf'fiti into which; the point of the supporting arm 28 willdropwhen the parts 'arevin the' proper position to commence the windingof a'core.

In an alternative meth'od of operation, the

core shaft is driven continuously insteadof intermittently as heretofore described. Thus as shown in Figures 6 and 7,"the core shaft may carry a spur gear engaged by a pinion (31 on shaft 62 which latter is driven 63 from the main drive shaft 26. W'it-h this construction the parts are so timed that the core shaft is being continuously rotated at relatively slow speed while the wire guide is oscillated to properly la; the wire in the slots.

To keep the wire under proper tension, I ha e shown the same in Figures 1 and 2 as being first lcd over a guide sheave 65 slid ably mounted on a support (36 and thence down under :1 second guide sheave 67 car l'i d by :1 spring support (38, the Wire passing fr m this last guide directly to the lrni rising gniijli.

it will lll nppnrrnt from tlu: foregoing I of mounting this guide enables the same being swung upward I the core will be rotated,either intermittently, as in the first instance, or continuously, in the case of the modified form of the invention, and that in this movement of the core, the wire will be interlaced to opposite sides of the radiating arms of the core, asshown in Figure 4.

t will be evident also that as the convolutions build up in the'slots, the variation in angularity between the wire and core will berompensated for by the automatic lowerin movement'ofth traversing wire guide, sa d guide by such lowering motion serving to keep the wire clear; of the corners of the radiatin armsandjto seat the wire firmly in th'esl ots provided therefor. In addition to the straightening and tensioning effect exerted on the-wire by the guide sheaves 65, 67, a braking? jorce may be applied to the wire tocau'seit to'lie snugly alongside the arms and in the slots provided. in the core disd.
